Running FLTK in static initializers (cont'd):

Browse Source 
1) Changed the way fluid attaches images to widgets and menu items so
it is compatible with running fluid-generated code containing such images
in a static initializer. Images are now attached calling a function:
  widget->image( image_function_name() );
and this function is defined before in fluid-generated code as:
   static Fl_Image *image_function_name() {
     static Fl_Image *image = new image_type(......);
     return image;
   }

2) Changed src/Fl_File_Chooser.fl so the source code generate by fluid
from it is compatible with running in a static initializer.

3) Changed src/Fl_File_Chooser.cxx and FL/Fl_File_Chooser.H
to the result of running fluid on src/Fl_File_Chooser.fl
